Borrower expectations about interest rates showed 44% thought rates would rise within the next year, 19% thought it would take longer, and 37% did not expect a rise.
Nick Chadbourne (pictured), CEO at LMS, said: “Borrowers choose short-term certainty, steering towards 2-year fixed-rate products.
“July’s remortgage market showed signs of shifting borrower behaviour, with a substantial rise in completions, which suggests many homeowners acted quickly to secure new deals.
“Most borrowers have favoured short-term certainty, with 2-year fixed-rate products becoming the most popular choice.”
Chadbourne added: “While monthly repayments increased for many, the desire to manage costs and secure financial stability remained a key driver.
“Further spikes are likely to occur around quarter-end, which is when more fixed-rate products expire. Until then, I’m expecting activity to remain steady.”
